UNITED STATES PATENT oEFlcE This invention relates to closures, and its general object is to provide a stopper that is primarily vdesigned for bottles preferably of the so-called vacuum type which includes a cap, but in any 5 event my stopper is held in closed position against casual displacement or removal by spring cushioning means for disposal between the cap and stopper to exert pressure upon the latter, with the result it is unnecessary to twist or strike the stopper in placing or removing the same, therefore the liability of breaking the liquid container is eliminated, and a leak proof connection is assured, yet the stopper can be easily and expeditiously removed.

A further object of the invention is to provide a stopper of the character set forth for all types of containers to which it lcarl be applied, and the stopper is simple in construction, inexpensive to manufacture and extremely eiliclent in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a view partly in section, showing my stopper applied to one type of vacuum bottle.

Figure 2 is a similar view showing its application to another type.

Figure 3 is a sectional view taken approximately on line 3--3 of Figure 1, looking in the direction of the arrows.

Figure 4 is a vertical sectional view taken through the stopper per se with parts in elevation.

Referring to the drawing in detail, it will be noted that I have illustrated my stopper applied to vacuum bottles, but I want it understood that it can be applied to all types of containers of the kind suggested, and especially ones that employ a cap forming part of the closure, as a cap or other abutting means is necessary in the use of my stopper.

The distinction between the bottles or the bottle containeraas illustrated in Figures 1 and 2 lies solely in the cap, and the cap I of Figure 1 is threadedly secured to the neck of the bottle container 2, while the cap 3 of Figure 2 extends about the upper portion of the bottle container 4 and is threadedly secured thereto. My stopper is similar in both instances and includes the usual 2 Claims. (Cl. 215-83) closure stopper or compresslble neck receiving body 5 which is generally made from cork, as suggested in the drawing.

Secured to the upper surface of the closure stopper 5 and centrally thereof, through the instrumentality of suitable means, such as a screw 6, is what I term a lug disk 1, in that it has formed thereon at equidistantly spaced intervals about the periphery thereof upwardly extending lugs 8 of the barrel type. The screw 6 is provided with a flat head and countersunk in the disk, as best shown in Figure 4. v

The lower convolution of the coil spring 9 is received in the lugs 8 that bind aboutthe same in order to fix the spring thereto, and it will be noted that the spring is of the graduated type with the convolutions thereof being of a size to fit one within the other, with the smallest convolution lowermost, as shown.

Receiving the upper convolution of the coil spring 9 is what I term a crown disk IIJ in that it -is substantially dome-shaped and has formed with its periphery an annular inturn flange Il providing a channel to receive and grip the upper convolution so that the crown disk is xed thereto.

In the use of my device, the stopper is placed in the neck of the bottle or liquid container and the cap is applied to the body of the bottle container in the usual manner, consequently the cap contacts the crown disk and compresses the coil spring, therefore exerting pressure upon the closure stopper so that casual removal or displacement is impossible.

Instead of the stopper 5, as shown, I may employ a gasket carrying disk member to contact the upper end of periphery of the neck of the bottle or liquid container. It will be obvious that the coil spring 9 may be reversed from the position as shown, or in other` words the large convolution may be disposed lowermost and secured to the stopper 5 or a gasket carrying disk; while the small convolution may be secured to the crown disk I0.

Again,'the disk 1 does not necessarily have to be connected or secured to the member 5 or gasket carrying disk above mentioned, and can merely rest thereon. The disk 1 can likewise be secured to the member 5, and the lugs 8 eliminated. In that event the disk 1 will act as an abutting means for the lower convolution of the coil spring 9 which may have its upper convolution secured to the cap, if desired.

It is thought from the foregoing description
